Abstract

Systems and methods for limiting access to imaging device consumable components are disclosed. In one embodiment, a system and a method pertain to receiving authorization information from a user, determining whether the authorization information is valid, and preventing specific access to a consumable component if the authorization is not valid.

Claims

1. A method for limiting access to consumable components in an imaging device, comprising:

receiving authorization information from a user;

determining whether the authorization information is valid; and

preventing specific access to a consumable component if the authorization information is not valid.

2. The method of claim 1, wherein the step of receiving authorization information comprises receiving an authorization code.

3. The method of claim 2, wherein the step of receiving authorization information comprises receiving an authorization code entered by the user via a control panel of the imaging device.

4. The method of claim 1, wherein the step of preventing specific access comprises engaging a locking mechanism.

5. The method of claim 4, wherein the step of engaging a locking mechanism comprises locking a carousel in which a consumable component is housed such that the carousel cannot be rotated.

6. The method of claim 1, wherein the step of preventing specific access comprises not disengaging a locking mechanism.

7. The method of claim 6, wherein the step of not disengaging a locking mechanism comprises not disengaging a locking mechanism that locks an access door that leads to the consumable component.

8. The method of claim 1, further comprising enabling access to a consumable component if the authorization information is valid.

9. The method of claim 8, wherein the step of enabling access comprises controlling a locking mechanism such that the locking mechanism will not disengage when an interior of the imaging device is accessed.

10. The method of claim 8, wherein the step of enabling access comprises unlocking an access door that leads to the consumable component.

11. A system for limiting access to consumable components in an imaging device, comprising:

a locking mechanism that is configured to selectively prevent access specifically to a consumable component; and

a consumable security manager configured to control the locking mechanism in response to authorization information provided by a user who wishes to access the consumable component.

12. The system of claim 11, wherein the locking mechanism is configured to prevent rotation of a carousel in which at least one consumable component is disposed.

13. The system of claim 11, wherein the locking mechanism is configured to lock an access door that leads to the consumable component.

14. The system of claim 11, further comprising an exterior door sensor that is configured to detect and signal when an exterior door of the imaging device is open.

15. The system of claim 14, wherein the consumable security manager locks the locking mechanism when invalid authorization information is received and the exterior door is opened.

16. A consumable security manager stored on a computer-readable medium, comprising:

logic configured to prompt a user for authorization information;

logic configured to receive entered authorization information;

logic configured to determine whether the entered authorization information is valid; and

logic configured to prevent access specifically to a consumable component if the authorization information is invalid.

17. The manager of claim 16, wherein the logic configured to prevent access comprises logic configured to engage a locking mechanism.

18. The manager of claim 17, wherein the logic configured to prevent access comprises logic configured to engage a locking mechanism that prevents rotation of a carousel in which a consumable component is housed.

19. The manager of claim 16, wherein the logic configured to prevent access comprises logic configured to not disengage a locking mechanism.

20. The manager of claim 19, wherein the logic configured to prevent access comprises logic configured to not disengage an access door locking mechanism that locks an access door that leads to the consumable component.

21. An imaging device, comprising:

a print engine;

a removable consumable component;

a consumable component locking mechanism;

a processing device; and

memory containing a consumable security manager configured to determine whether authorization information provided by a user is valid and, if not, control the locking mechanism such that the consumable component cannot be removed when an interior of the imaging device is accessed.

22. The imaging device of claim 21, further comprising an exterior door that provides access to the imaging device interior and an exterior door sensor that is configured to detect when the exterior door is open.

23. The imaging device of claim 22, wherein the consumable security manager is configured to engage the locking mechanism when invalid authorization information is provided and the exterior door is opened.

24. The imaging device of claim 23, further comprising a carousel in which the consumable component is housed, wherein engaging the locking mechanism comprises engaging the carousel such that it cannot rotate.

25. The imaging device of claim 21, wherein the consumable security manager is configured to release the locking mechanism when valid authorization information is provided.

26. The imaging device of claim 25, further comprising an access door that leads to the consumable component, wherein releasing the locking mechanism releases the access door.

27. A locking mechanism used to limit access to a consumable component in an imaging device, comprising:

a locking member that is configured to engage a drive gear of a carousel that houses the consumable component when valid authorization information has not been provided such that the carousel cannot be rotated.

28. A locking mechanism used to limit access to a consumable component in an imaging device, comprising:

a locking member that secures an access door that leads to the consumable component, wherein the locking member is further configured to only disengage to release the access door when valid authorization information is provided.

29. A system for limiting access to imaging device consumable components, comprising:

means for selectively preventing access specifically to a consumable component; and

means for controlling the means for selectively preventing access, the means for controlling being responsive to authorization information provided by a user who wishes to access the consumable component.

30. The system of claim 29, wherein the means for selectively preventing access comprises a locking mechanism and wherein the means for controlling comprises a consumable security manager.
